Boot Root Cause Step Degradation Bits RRS feed

  • Question

  • Hi, my pc became very slow after Windows 10 upgrade.
    Below you can find the Event Viewer log Microsoft-Windows-Diagnostics-Performance/Operational.

    Especially lines:

    -BootMachineProfileProcessingTime 190886
    -BootRootCauseStepDegradationBits 6291456

    What does it means "Boot Root Cause Step Degradation Bits" ?  Is it related to "Boot Machine Profile Processing Time"?

  • Quite a bit of OS data...Chk with youre pc mfg to make sure its Win 10 compatable...If good,then in Win,open

    cmd prompt,type:  CHKDSK C: /F  agree to restart,type: EXIT restart pc   Also,if Win doesnt start,tap the F8

    key on pc start-up,select  safe-mode in cmd,type same as above..Also,you need to type in cmd:  Sfc /Scannow

    any way you can in Windows,this chks/repairs Win OS folders-files,once done in cmd,type in CHKDSK C: /F

    the repairs are thry MS-DOS (restart)..
